DETAILED DESCRIPTION

Example embodiments will become more readily understood by reference to the following detailed description of the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as being limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete. Like reference numerals refer to like elements throughout the specification.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, and/or elements, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or groups thereof.

It will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on”, “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer or section from another region, layer or section. Thus, a first element, region, layer or section discussed below could be termed a second element, region, layer or section without departing from the teachings set forth herein.

Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Some example embodiments are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures). As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, these example embodiments should not be construed as limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing. For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of this disclosure.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and this specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Unless specifically stated otherwise, or as is apparent from the discussion, terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical, electronic quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

As disclosed herein, the term “storage medium”, “computer readable storage medium” or “non-transitory computer readable storage medium,” may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other tangible machine readable mediums for storing information. The term “computer-readable medium” may include, but is not limited to, portable or fixed storage devices, optical storage devices, and various other mediums capable of storing, containing or carrying instruction(s) and/or data.

Furthermore, at least some portions of example embodiments may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware or microcode, the program code or code segments to perform the necessary tasks may be stored in a machine or computer readable medium such as a computer readable storage medium. When implemented in software, processor(s), processing circuit(s), or processing unit(s) may be programmed to perform the necessary tasks, thereby being transformed into special purpose processor(s) or computer(s).

When the terms “about” or “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value include a tolerance of ±10% around the stated numerical value. The expression “up to” includes amounts of zero to the expressed upper limit and all values therebetween. When ranges are specified, the range includes all values therebetween such as increments of 0.1%. Moreover, when the words “generally” and “substantially” are used in connection with geometric shapes, it is intended that precision of the geometric shape is not required but that latitude for the shape is within the scope of the disclosure.

According to some example embodiments there is provided an aerosol-generating device (also called a vapor-generating device). The device comprises a device housing comprising at least two receiving chambers for receiving and accommodating (“configured to receive and accommodate”) a consumable in each one of the at least two receiving chambers.

In some example embodiments, each receiving chamber of the at least two receiving chambers may comprise one of a heating element configured to heat a consumable accommodated in the respective receiving chamber or electrical contacts connectable to an external heating element of a consumable, where the external heating element is configured to heat the consumable accommodated in the respective receiving chamber, or an induction coil configured to heat a susceptor material provided in the device or in the consumable.

The device may further comprise at least two mouthpieces, wherein each mouthpiece of the at least two mouthpieces, in response to being mounted to the device housing, cover a receiving opening of a receiving chamber of the at least two receiving chambers.

An airflow into and out of each mouthpiece of the at least two mouthpieces may be kept separate from the airflow into and out of each of the other of the at least two mouthpieces. Restated, the aerosol-generating device may isolate airflows through separate, respective mouthpieces of the at least two mouthpieces.

With this device, each receiving chamber is accessible via a separate mouthpiece. Thus, each consumable arranged in the receiving chambers is accessible via a separate mouthpiece. At least two, preferably different, consumables may be accommodated in the device and are then in a state ready to be used by a user (also called an adult vaper) without further preparation of the device. For example, no repositioning of a mouthpiece is required if one of the consumables is selected for being used. In particular, a switching between different consumables, for example between subsequent puffs (e.g., between separate draws of air through an airflow path of the aerosol-generating device via one or more mouthpieces by an adult vaper), is readily available. In addition, different receiving chambers and respective mouthpieces may individually be used only for specific types of consumables. The assignment of one mouthpiece to one receiving chamber prevents contamination of a receiving chamber and respective mouthpiece with substances from a consumable accommodated in another receiving chamber. This may enhance a sensory experience provided by the device over a longer period of use of the device.

The aerosol-generating device provides an adult vaper with the choice which consumable accommodated in the receiving chamber shall be used, subsequently or alternatingly and to what extent. Depending on the type (“kind”) of consumables provided in the receiving chambers a desired consumer experience may be selected spontaneously. For example, a spontaneous selection may be made between a flavor-based experience or a nicotine-based experience.

In some example embodiments, each mouthpiece of the at least two mouthpieces comprises an inlet opening and an outlet opening. Each of the inlet openings are aligned with a receiving opening of one of the at least two receiving chambers, and thus may be aligned with a separate consumable of at least two consumables accommodated in separate receiving chambers of at least two receiving chambers. Each of the outlet openings are individually accessible by an adult vaper. Thus, puffing (e.g., drawing air through at least one airflow pathway from an inlet opening to an outlet opening and through an aerosol-generating device) at any of the mouthpieces is available anytime. Depending on the consumable accommodated in the receiving chamber associated with the respective mouthpiece the adult vaper is drawing air through the aerosol-generating device at, a respective sensory experience is provided.

The mouthpieces may be separate, independent device parts. This enables each receiving chamber to be opened and closed separately (“independently”), for example for a removal or replacement of a consumable.

The mouthpieces may form a mouthpiece unit (also called a mouthpiece assembly). Restated, an aerosol-generating device may include a mouthpiece assembly that includes at least two mouthpieces. Thus, the at least two mouthpieces may be connected, for example integrated into an assembly of mouthpieces. By this only one device part needs to be manufactured and assembled with a device housing. In addition only one device part needs to be handled to gain access to all receiving chambers of the device at a same time.

A device may comprise mouthpieces all being separate device parts. A device may comprise mouthpieces being separate device parts and a mouthpiece assembly. A device may comprise one or more mouthpiece assemblies. For example, a device may comprise a mouthpiece assembly, for example, comprising two connected mouthpieces and one or more individual mouthpieces. A device may, for example also comprise two mouthpiece assemblies, each comprising for example two connected mouthpieces.

In some example embodiments, the at least two mouthpieces of the device may form a mouthpiece assembly. Advantageously, an airflow into and out of each of the at least two mouthpieces of the mouthpiece assembly may be kept separate for each of the at least two mouthpieces. By this, a mixing of evaporated substances from two or more consumables may be kept separate although the mouthpieces are assembled in one device part.

Substances from a substrate contained in the consumable may be transported by an airflow passing through the substrate or through the consumable, respectively. These substances may simply be entrained by the passing airflow. For example, an airflow passing a tobacco substrate may be entrained with tobacco flavor. The substances to be entrained may also actively be generated, for example, by heating a substrate contained in the consumable and forming an aerosol (also called a vapor). Also other atomization processes may be used for aerosol generation.

In the device, preferably, at least one of the at least two consumables is heatable.

In the device, all consumables may be heatable.

Advantageously, for aerosolization (also called or including vaporization) of a consumable or of substances comprised in the consumable, the substrate is heated. This may be done by heating the substrate via heating element in the consumable or by providing a heating element in the device. If a heating element or another atomization element is comprised in the consumable itself, a receiving chamber preferably comprises respective electrical contacts for connecting an electrical power source in the device to the consumable for providing the required power to the atomization element, for example heater, in the consumable.

Heating of a consumable is preferably performed resistively or inductively. A resistively heatable heating element may be provided in the device or in the consumable. With inductive heating, an inductor, for example an induction coil, is preferably provided in the device. A susceptor material heated by the inductor may be provided in the device or in the consumable.

Preferably, at least one receiving chamber of the at least two receiving chambers comprises a heating element for heating a consumable accommodated in the respective receiving chamber or comprises electrical contacts connectable to an external heating element of a consumable for heating the consumable accommodated in the respective receiving chamber.

One receiving chamber may comprise a heating element and another receiving chamber may comprise electrical contacts.

Both of the at least two receiving chambers may comprise both, a heating element and electrical contacts for example for an external atomization element. This provides many options for different consumables to be included in the aerosol-generating device according to some example embodiments. This also facilitates use of the device by not having to check if a receiving chamber is adapted for a specific consumable or aerosolization option.

A heating element in the device may be arranged in a receiving chamber wall. For example resistively heatable metal tracks may be arranged at a receiving chamber wall or resistively heatable wires may be arranged in the receiving chamber wall. An inductor in the form of an induction coil may be arranged in a receiving chamber wall and surround a consumable accommodated in the receiving chamber.

A heating element in the device may extend into a receiving chamber. For example, the heating element may be a resistively heated heater blade or an elongated susceptor. At least one of the receiving chambers may comprise a heating element extending into the receiving chamber.

Various types of consumables may be used or may be determined to be usable with the aerosol-generating device according to some example embodiments.

Examples of consumables are, for example, but not limited to: liquid containing cartridges (also called reservoirs) or tank systems including or excluding an integrated aerosolization element (also referred to as an integrated vaporizer assembly) such as for example cartomizers (also called cartridges, a combined reservoir and atomizer); solid substrate containing consumables such as for example tobacco containing plugs; solid substrate containing capsules, wherein the solid substrate may be tobacco material, homogenized tobacco material or substrate in powder form; vaporizable wax; tobacco sheets that are gathered or crimped.

In some example embodiments, a tobacco material may include material from any member of the genus Nicotiana. In some example embodiments, the tobacco material includes a blend of two or more different tobacco varieties. Examples of suitable types of tobacco materials that may be used include, but are not limited to, flue-cured tobacco, Burley tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, dark tobacco, blends thereof and the like. The tobacco material may be provided in any suitable form, including, but not limited to, tobacco lamina, processed tobacco materials, such as volume expanded or puffed tobacco, processed tobacco stems, such as cut-rolled or cut-puffed stems, reconstituted tobacco materials, blends thereof, and the like. In some example embodiments, the tobacco material is in the form of a substantially dry tobacco mass.

The receiving chambers may accommodate different types of consumables, for example a liquid containing reservoir and a solid substrate containing consumable, preferably a solid tobacco substrate containing consumable.

Different consumables may differ in shape, for example, in a diameter. Preferably, different consumables contain any one or a combination of different aerosol-forming substrate (also called a vapor-forming substrate), for example different tobacco material, different flavor, different nicotine content, different substance combination. Preferably, different consumables comprise a different way of being heated or in general a different way the substance of the consumable is atomized. Different consumables may comprise both different aerosol-forming substrate and a different way of atomizing the substrate.

The receiving chambers may comprise consumables of a same kind, for example liquid containing reservoirs. Preferably, the reservoirs then contain a different liquid, for example having different flavor or different substance combination.

The consumables may make use of different methods for releasing substances from the consumables. For example, when one consumable in one receiving chamber comprises a heatable liquid, another consumable in another receiving chamber may be a non-heated tobacco substrate or may contain a non-heated but otherwise atomized substrate.

Preferably, the at least two receiving chambers are arranged parallel and next to each other in the device housing. Preferably the at least two receiving chambers are arranged in a line next to each other. The receiving chambers may also be arranged in a closed packed manner. For example, three receiving chambers may be arranged in a triangle or four receiving chambers may be arranged in the form of a parallelepiped.

In some example embodiments, each receiving chamber may be elongate and have a longitudinal axis. The at least two receiving chambers may be arranged next to each other in the device housing with their longitudinal axes in parallel.

‘Arranged parallel’ is herein meant that a longitudinal axis of the receiving chambers is arranged parallel. The longitudinal axis is typically arranged along an insertion direction of a consumable into the receiving chamber. Receiving chambers arranged parallel and next to each other have their receiving openings directing in a same direction such that the receiving chambers may be filled from a same, for example top, direction.

In some example embodiments, each receiving chamber is elongate and has a longitudinal axis and the at least two receiving chambers are arranged in the device housing such that the longitudinal axes of the at least two receiving chambers extend in different directions. In other words, the at least two receiving chambers may be arranged such that their longitudinal axes are not in parallel.

The at least two receiving chambers may be arranged in the device housing such that the longitudinal axis of the at least two receiving chambers include an alignment angle. The alignment angle is larger than 0 degree.

If the receiving chambers are arranged including an alignment angle in between neighboring receiving chambers, then the receiving openings of the receiving chambers are preferably arranged flush with a circumference of the device housing.

Mouthpieces may be removably connected to the device housing.

Mouthpieces may be completely disassembled or may only partly be removed from the housing for gaining access to the receiving chambers. Mouthpieces may be connected to the device housing, for example, in a hinged manner (e.g., via a hinge).

Preferably, each mouthpiece is connected to the device housing in a hinged manner. Thereby, each mouthpiece is individually connected to the device housing by a separate hinge. All or some of the mouthpieces may also form a mouthpiece assembly, which assembly is connected to the device housing in a hinged manner. Depending on the construction of the mouthpiece assembly, one or more hinges may be provided.

The consumables may partially or entirely be inserted into a receiving chamber. A partial insertion facilitates the removal of the consumable after use. Thereby, an adult vaper may grip an extending portion of the consumable.

Removal of a consumable from a receiving chamber may also be facilitated by the provision of cutouts in the device housing that enable a gripping of the consumable. Preferably, two oppositely arranged cutouts are provided in a receiving chamber.
